- `containr nodes add <user@host>` mints an enroll token, SSHes once,
runs the install script remotely; --print emits the one-liner
- Public /api/agents/install.sh + /api/agents/download/{platform};
agent binaries built into the image under /agents
- Agent-side `prune` (bounded docker system prune, volumes opt-in)
and `system_df` commands
- node_agents.auto_prune + health sweep enqueues daily prune;
offline/online transitions notify admins
- CLI nodes update/prune/commands + MCP tools (prune confirm-gated)
- Usage page: install one-liner, per-node Prune + auto toggle
